[0001] The utility model relates to a welding slag processing device, in particular to a welding slag collecting device. Background Art

[0002] In the manufacturing process of the boom of the boom aerial work platform, after the boom cylinder is assembled, the boom cylinder needs to be primed. During the primed welding process, a large amount of spattered welding slag will be scattered from the welding pool to the inner wall of the boom cylinder. Since the boom of the boom aerial work platform is in the shape of a long rod and has a small cross-section, it is difficult to handle the spattered welding slag inside the boom cylinder after welding. Therefore, it is necessary to solve the spattering problem of welding slag inside the boom cylinder during the primed welding process.

[0003] The prior art places a slag basin at a corresponding position below the weld inside the boom cylinder to collect the spattered slag. The slag basin can only solve the slag problem on one side of the weld. When welding the other side, the slag basin needs to be manually moved out, and after the boom cylinder is turned over, the slag basin needs to be moved back into the boom cylinder. The spattered slag is easy to spread around. Since the boom cylinder is in the form of a long pole and the cross-section of the boom cylinder is small, it is difficult to handle and polish the spatter and slag inside the boom cylinder, which greatly affects production efficiency and product quality. In order to prevent the spattered slag from spreading to the inner wall of the boom cylinder, the prior art needs to increase the cross-sectional area of ​​the slag basin, which causes the slag basin to be too heavy, making the process of carrying the slag basin time-consuming and labor-intensive, and slowing down production efficiency.

[0004] In view of this, it is necessary to design a welding slag collection device that can overcome the above-mentioned technical difficulties and effectively solve or alleviate the above-mentioned technical defects. Utility Model Content

[0043] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0044] like Figure 1As shown, the welding slag collecting device of the present invention comprises a supporting mechanism 1 and a slag box 2, the slag box 2 is formed with an open mouth 16, the open mouth 16 is used to receive the spattered welding slag, the shape of the open mouth 16 is set to correspond to the weld on the material to be welded, the supporting mechanism 1 is used to hold the open mouth 16 against the plane where the weld of the material to be welded is located, so that the open mouth 16 is set corresponding to the weld, so that the slag box 2 and the plane where the weld is located cooperate to form a accommodating space 15 for collecting welding slag, because the slag box 2 of the welding slag collecting device of the present invention is held near the weld under the action of the supporting mechanism 1, the spattered welding slag generated when welding the weld will be collected by the slag box 2 before further diffusion, thereby ensuring that the spattered welding slag will not spread to the surface of the material to be welded, and the slag box 2 can be taken out after welding is completed, and it is easier to handle the spattered welding slag on the slag box 2 after it is taken out.

The slag box 2 of the utility model can complete the collection of the splashed weld slag before it further diffuses, so that the cross-sectional area of ​​the slag box 2 of the utility model is much smaller than the slag basin of the prior art, and then the weight of the slag box 2 is light, which is convenient for installation and transportation, and improves production efficiency. Among them, the material to be welded can be a boom, and the welding slag collection device of the utility model collects the welding slag splashed at the weld during the welding process of the boom.

The height adjustment mechanism 10 can provide support for the end of the slag box 2, so that the slag box 2 fits closely to the material to be welded, reducing the problem of self-weight deformation of the slag box 2, and is relatively easy to install. Since the first height adjustment support 11 and the second height adjustment support 12 are respectively threadedly connected to the two ends of the guide tube 13, the first height adjustment support 11 and the second height adjustment support 12 can be screwed in or out according to the internal height of the material to be welded to change the height of the height adjustment mechanism 10, so that the height adjustment mechanism 10 can adapt to materials to be welded with different internal heights.

The first support member 301 and the second support member 302 are slidably connected to the two ends of the guide tube 4. Springs are connected between the first support member 301 and the guide tube 4 and between the second support member 302 and the guide tube 4. The first support member 301 and the second support member 302 are both formed with a support portion 7 at one end away from the guide tube 4. The support portion 7 of the first support member 301 is formed with a mounting groove 18 for clamping the first slag box 201. The support portion 7 is formed with a mounting groove 18 for clamping the second slag receiving box 202. The adjustable support mechanism includes a thickness adjustment block 14 and a height adjustment mechanism 10. The thickness adjustment block 14 is formed with a clamping groove 9 for clamping the end of the arm frame. The clamping groove 9 is a stepped clamping groove. The steps of different heights on the stepped clamping groove correspond to arms of different thicknesses. One end of the first slag receiving box 201 and the second slag receiving box 202 are both connected to the thickness adjustment block 14. The height adjustment mechanism 10 includes a first height adjustment support 11, a second height adjustment support 12 and a height adjustment support 13. The guide tube 13, the first height adjustment support 11 and the second height adjustment support 12 are threadedly connected to the two ends of the height adjustment guide tube 13, and the first height adjustment support 11 and the second height adjustment support 12 are formed with a height adjustment support part 17 at one end away from the guide tube 13. The height adjustment support part 17 of the first height adjustment support 11 is formed with a mounting groove 18 for clamping the first slag box 201, and the height adjustment support part 17 of the second height adjustment support 12 is formed with a mounting groove 18 for clamping the second slag box 202.During installation, first adjust the length of the first slag box 201 and the second slag box 202 to be consistent with the length of the boom, align the openings 16 of the first slag box 201 and the second slag box 202 with the welds on both sides of the boom and extend them into the inside of the boom. When the extended length reaches half of the length of the boom, compress the spring of the adaptive support mechanism 19 so that the height of the adaptive support mechanism 19 corresponds to the height of the inner cavity of the boom, align the mounting grooves 18 on the support portions 7 of the first support member 301 and the second support member 302 with the first slag box 201 and the second slag box 202, respectively, and insert the adaptive support mechanism 19 between the first slag box 201 and the second slag box 202. 02 Apply a force to drive the middle part of the slag box 2 to be close to the arm, continue to put the first slag box 201 and the second slag box 202 until the end of the slag box 2 is aligned with the end of the arm, so that the arm is stuck in the stepped slot on the thickness adjustment block 14, so that the open mouth 16 of the slag box 2 at one end is close to the plane where the weld is located, put the height adjustment mechanism 10 into the end of the arm away from the thickness adjustment block 14, so that the installation groove 18 on the height adjustment support part 17 of the first height adjustment support member 11 and the second height adjustment support member 12 respectively corresponds to the first slag box 201 and the second slag box 202, adjust the height adjustment mechanism 10 so that its height corresponds to the inner cavity height of the arm, and complete the installation of the welding slag collection device. The height adjustment mechanism 10 makes the open mouth 16 of the slag box 2 at the other end abut against the plane where the weld of the arm is located, so that both ends and the middle of the slag box 2 can be close to the plane where the weld is located, reducing the self-weight deformation of the slag box 2 and making the installation of the welding slag collection device more stable. Since the first slag box 201 and the second slag box 202 are both pressed against the plane where the weld is located by the support mechanism 1, the open mouth 16 and the plane where the weld of the arm are located form a receiving space 15, so that the spattered welding slag generated during welding can be received by the slag box 2 before diffusion.

After completing the collection of the welding slag on one side, the welding slag collection device can be collected through the slag box 2 on the other side without adjusting and reinstalling the welding slag collection device.After welding is completed, the arm cylinder is partially deformed. The thickness adjustment block 14 of this embodiment is more convenient to install than the height adjustment mechanism 10. However, if thickness adjustment blocks 14 are used on both sides, it will be difficult to remove the arm cylinder after it is deformed. Therefore, the utility model uses a thickness adjustment block 14 on one side and a height adjustment mechanism 10 on the other side. During disassembly, the height of the height adjustment mechanism 10 is first adjusted, the height adjustment mechanism 10 is taken out, and then the thickness adjustment block 14 is removed from the arm. Due to welding, the arm cylinder is partially deformed, and the adaptive support mechanism 19 of this embodiment can make adaptive adjustments according to the deformation of the arm, so that the process of removing the slag box 2 is smoother.
